The first step in the production process of 2,7-diiodo-9,9-dimethyl-9H-fluorene is the synthesis of 9,9-dimethyl-2,7-dibromo-9H-fluorene.
This is accomplished by a reaction between 2,7-dibromo-9H-fluorene and methyl iodide in the presence of a catalyst such as sodium hydride.
The reaction is exothermic, and the mixture is cooled to prevent excessive heat buildup.

In the next step, the 9,9-dimethyl-2,7-dibromo-9H-fluorene is treated with hydrogen bromide in the presence of a solvent such as acetic acid.
This reaction decomposes the dibromide to form the corresponding aldehyde, which is then reduced to the corresponding alcohol using a reducing agent such as lithium aluminum hydride.

The alcohol is then treated with chloroform and a strong acid such as hydrochloric acid to form the corresponding chloride.
This chloride is then heated in the presence of a solvent such as acetic acid and a catalyst such as zinc chloride to form the corresponding nitrile.

In the final step, the nitrile is treated with sodium amide in a solvent such as N,N-dimethylformamide to form the desired 2,7-diiodo-9,9-dimethyl-9H-fluorene.
The product is then isolated and purified by standard techniques such as crystallization, filtration, and chromatography.
